In recent years, newly sworn-in Australian prime ministers have taken to scurrying across the Tasman to meet their New Zealand counterpart as the concluding rite of passage.
No doubt when Malcolm Turnbull and John Key meet the media in front of a display of almost identical national flags on Friday, there'll be talk of our unique closeness as nations. The special relationship will be dusted down, as will our shared military exploits, brothers in arms, blooded in battles from the Boer Wars in South Africa to present-day Iraq.
There'll be sibling rivalry about who will bring home the Rugby World Cup, and loyal toasts to our shared Queen.
From the New Zealand end of the telescope, this new emphasis on mateship by the Australian leadership has a whiff of hypocrisy. It coincides with yet another move by Australia to drive a wedge between two peoples who have, for most of our short histories, regarded ourselves as one.
Until 2001 we were effectively moving back and forth across the Tasman seeking work in one big market. My mother, for example, was born in Perth. Her parents were migrants from England and Europe. They spent time in Kalgoorlie before settling in Auckland. In the 1970s, two of my brothers made the return trip, settling in Sydney. As was the tradition, they retained their New Zealand citizenship, but enjoy all the rights of Australian citizens.
